[coreboot] Spi device pci disabled on braswell

[sebastien basset]

Hello,

i used same config cyan motherboard for intel braswell.i want use sio spi,
gpio multiplexing is configured for SPI,
device tree is activated for pci device SPI. I don't see this pci device in
coreboot & kernel, can you help me ?


-- My configuration:

Gpio Multiplexing:

179 V14 SPI1_CLK 1 SPI1_CLK V1P8A 0 (20k PU) 0

180 Y13 SPI1_CS0_N 1 SPI1_CS0_N V1P8A 1 (20k PU) 1

181 Y12 SPI1_CS1_N 1 SPI1_CS1_N V1P8A 1 (20k PU) 1

182 V13 SPI1_MISO 1 SPI1_MISO V1P8A Input (20k PU) Input (20k PD)

183 V12 SPI1_MOSI 1 SPI1_MOSI V1P8A 0 (20k PU) 0

I used mode 1.



In device tree of coreboot:

register "lpss_acpi_mode" = "0"
    device pci 1e.5 on end    # 8086 228e -   SPI 1
   device pci 1e.6 on end    # 8086 2290 -   SPI 2
   device pci 1e.7 on end    # 8086 22ac -   SPI 3
